  	  in U-Boot.  This is helpful if you are debugging code that
  	  executes before the console is initialized.

  		help
  		  Say Y here if you wish the debug print routes to direct
  		  their output to an 8250 UART.  You can use this option
  		  to provide the parameters for the 8250 UART rather than
  		  selecting one of the platform specific options above if
  		  you know the parameters for the port.
  
  		  This option is preferred over the platform specific
  		  options; the platform specific options are deprecated
  		  and will be soon removed.
